LOL! In theory it sounds good. But ... Coins were made round for a reason (stackable, readable, practical). Usability reasons. And even lower production costs. Changing that would be one of those improvements that is not an improvement.

Some think the term "pieces of eight" refers to this, but it's not the case. http://colonial-america.suite101.com/article.cfm/pieces_of_eight_not_just_pirate_money Your coin idea is actually quite an old one: Back when Spanish dollars and doubloons used to be made of silver and gold, DIY fractions of full coins were often created by simply chopping the coin in half, or quarters, or eighths, with an axe.
